SPECTRAL MAGNETOELLIPSOMETER WITH DEVICE FOR MAGNETO-RESISTIVE MEASUREMENTS Russian patent published in 2015 - IPC G01N21/21 B82B1/00 

FIELD: instrumentation.

SUBSTANCE: magnetoellipsometer contains a radiation source with a monochromator, a polariser armfitted with a position switch from 0° to 45°, a magnetic system for effecting a sample, an analyser arm of an ellipsometer fitted with the position switch from 0° to 45°, the controller with a detector for synchronous measurement of light fluxes, and also the magnetoresistance measurement unit assembled according to the quadripolar measuring bridge circuit and consisting of three resistors and one replaceable module designed as a substrate onto which the witness sample is sputtered with the composition identical to that of the studied sample, and the magnetic system is designed as a pair of optimised Helmholtz's coils and perpendicularly located solenoid.

EFFECT: expansion of functionality of the ellipsometer verification method, improvement of accuracy of measurements, obtaining the additional information on electric or magnetic properties within a uniform method.
